While staring at something I have warmed on the stove, I thought of the condensation, the distillation, then the extraction.. hmm Gregar extractor?
How could you rearrange that thing... aha! Simple enough that surely it's been posted here before, but I'm wondering if it has?
There's been enough chat about said extractor that I think I'll post this.

Take a closed jar, or tub, or whatever, with solvent 1 in it. Add heat (warm stove, sun, hotplate..), solvent evaporates and condenses on 2, which
has a cooled cone on top (like the "survival still" plan). Condensate drips into container 3 (optionally set on a stand), holding sample to
be extracted. As distillate fills 3, it overflows into 1.

I figure this would be a good way to do things if you have a lot of time to wait for something... sit it in the sun and forget about it for a few
weeks. It would of course go faster on a hotplate and/or with cooling air or water on the top.

Depending on whether or not your materials are corrosive or require high heat, you could use wood, plastic, metal, glass, whatever you want.

Ah, so it is...(I don't know why I haven't looked up Soxhlet until now). They are pretty similar, it just looks like Gregar runs
continuously or dripwise rather than toilet-flush-wise ( , well it does say
siphon on the Soxhlet, so it must have a lot more hysteresis).

Yeah, a narrow mouth would be better, and the whole thing would work much better in a squat container, if you can get one.
